Biden was the most fanatical supporter of Israel in the 80s. Even Ronald Reagan told Israel to GTFO out of Beirut when he saw the barbarity of the IDF in the early 80s. He said to the then PM of Israel that they were doing a holocaust. Even when the PM tried to admonish Reagan by telling him ‘don’t tell me about holocaust, I know about the holocaust’ Reagan told him to fuck off and withdraw or he will withdraw support.
After hanging up Reagan turned to an aide and said ‘I had no idea I had that kind of power’.
